Product Description
Diamond Eye BC350S304 is a 3.5" Torca-style preformed band clamp built from 304 stainless steel. It delivers an even, 360° seal on butt-joint (end-to-end) exhaust connections without crushing tubing — perfect for clean, serviceable joints on diesel and heavy-duty setups.
- Material: 304 stainless steel (corrosion-resistant)
- Connection type: Butt-joint (end-to-end), not lap-joint
- Uniform clamping force with preformed band + reaction block design
- Metric hardware, reusable and serviceable
Fitment
Universal for 3.5 inch (89mm) OD exhaust tubing where a butt-joint band clamp is required. Works on diesel truck systems and universal fabrication projects. If you need a lap-joint clamp (overlap/ID-to-OD), see our 3.5" lap-joint options in the clamps category.

Helpful Notes
- Butt-joint vs. lap-joint: This clamp is for straight end-to-end joints. For overlapped slip joints, use a lap-joint clamp.
- Always install over clean, properly aligned tubing for best sealing.
- Re-torque after first few heat cycles.

FAQ
Is this clamp for butt-joint or lap-joint connections?BC350S304 is a butt-joint Torca band clamp for straight end-to-end pipe joints. For overlapped slip joints, use a lap-joint clamp.
Will 304 stainless hardware resist corrosion on winter/salt roads?Yes, 304 stainless offers excellent corrosion resistance. Rinse road salt periodically for maximum longevity.
What torque should I use?Typical Torca band clamps are tightened to ~40–45 ft-lb. Verify by feel and re-check after heat cycles; do not overtighten to the point of band deformation.
Can I reuse the clamp?Yes. Torca band clamps are serviceable and can be re-used if undamaged. Inspect the band and hardware before reinstallation.
